Lunched mobo?

TheBeginner · 5 Apr 2008 at 23:44

Hi,

I have an Asus P5B-Deluxe. Latest Bios (1226) in place.

Recently upgraded to an E8400. This went fine and it seemed that the RAM was holding it back so I bought some new RAM. It started playing up - random bluescreens, refusing to boot and then booting fine. I changed the RAM back in case I had some dodgy new RAM. Same problems occurred. Then the HD crashed and I was unable to boot in to windows. New HD and a new Vista 32 HPremium install and I'm getting random problems again.

I reckon I've cracked the board or done something to it and it is now effectively SNAFU.

Before I buy a new mobo, can anyone suggest what else might be the cause of the woes? The graphics board has not been touched but is an ECGA 8800GTS (640Mb).

If I do go for another mobo, what are people using that will allow me to run my E8400 at 4GHz and supports PC8500 RAM?

Cheers,

Ok, just because you have an 8400 doesnt guarantee it will hit 4Ghz
(stable)

I have no idea what a Lunched mobo means or indeed SNAFU

but i would suggest you running a memtest of your system at stock settings first, with bios at defaults before ruling out the motherboard

Reset everything to defaults, no overclocking and format and reinstall Windows. See if the errors continue.

Certainly not in a P965 board anyway.

Lunched = broken
SNAFU = Situation Normal, All ****** Up (US Military slang)

I put everything back to stock when the fault statrted to see that were the problem. The faults continued. I'll try memtest to see if that flags any problems.

What would you suggest as a more suitable board for a try for 4GHz?

Done, done, done and yes faults continued.

I've reinstalled Windows a couple of times but it now appears be running ok.

It's odd that it was happy overclocking to 3.8+ on the E8400 before the problems but now throws a fit if I do anything to it.

Chip degredation?

I think it's unlikely to be CPU degradation. The P965 chipset doesn't officially support the E8xx0 series, so I'd say he's lucky to have got any kind of overclock at all, never mind an unstable one. Get yourself a P35 board!

Interesting. I thought it was supported but on looking again, I see that the 1226 bios for the P5B Deluxe is a beta version. Might be one answer as to why the thing is a bit flaky! :eek:

As the thing is finally stable again at stock settings, I shall monitor the situation and see if the bios becomes an official version. If the pc still then won't play anymore above stock I'll investigate a new motherboard.

Thanks.
